DCC Accessory Decoders
Accessory Decoders or Stationary Decoders are decoders are made to control switches, turnouts, and signals on a model railway. They can also animate things such as crossing gates and semaphores.
The accessory decoders connect to a bus network such as LocoNet or the track and follow DCC rules.
They are much larger, and have outputs designed to drive switch machines or other fixed devices which provide mechanical actuation. They are electrical devices, and have no mechanical capacity.
Some stationary decoders can be configured to control slow motion switch machines, such as the Tortoise, or offer features such as routes.
